Temporary strainers offer excellent, low-cost protection for costly filtration equipment, valves, and other mechanical equipment.
Excellent for pipeline start-up or minimal solid loading.
Custom sizes, configurations, construction materials and other options may be available.
Materials of Construction
The materials of construction of a strainer should be compatible with the fluid. Most commonly used materials of construction are :
- Stainless Steel: 304, 306, etc.
- Monel Metal
Also available other materials may also be available, please contact YUBO.
10 mesh, 20 mesh, 30 mesh, 40 mesh, 60 mesh, 80 mesh, 100 mesh.
For mesh-lined strainers, flow direction must be specified.
Open area: the available range in the open area of the strainer to the cross section of the pipe is 100% to 300%.
1. Installation of a conical strainer can be done in one of two different ways: cone facing upstream or cone facing downstream.
2. When the cone is downstream, debris collects inside the cone near the tip, and the cone may rip apart due to heavy strain on the tip.
3. The advantage of the cone downstream side is easier removal of debris. But the mechanical strength of the cone shall be ensured.
4. When the cone is upstream, debris collects to the side of the strainer. Its advantage is that any plugging of the strainer will start in the outside and work its way in.

Please pay more attention to the viscosity flow rate, corrosiveness, temperature, and pressure drop of your liquid before you select.
To suit your existing system without any deviation, our temporary strainer dimensions are optional in actual manufacturing. You can refer to our standard technical data to choose from, or send us your independent sizes to custom.
1. If a strainer cannot withstand high temperatures or differential pressures, it could come apart and cause damage to equipment.
2. The expected pressure drop across the strainer should not cause the downstream operating pressure to fall below the minimum required pressure of the line e.g. NPSH for a pump.
3. The perforations of the strainer should be slightly smaller than the smallest piece of debris that is expected to flow through it.
4. If the perforations are too small, a high pressure drop could develop across the strainer and cause it to fail.
Smooth inner face with low friction coefficient
Highly resistant to corrosion and abrasion and impact
High mechanical properties and high fracture resistance
